- The figure depicts the sum of two velocities, vA and vB. The magnitude of the sum is 5.5 m/s and the angles shown in the image are θ1 = 31.8°, and θ2 = 16.7°. Find the magnitude of velocity vA in meters per second.Ih took Joseph 30 minutes longer to drive 375 km from along the north shore of a river from Apex to Rounder than it took to return along the south shore, a distance of 420 km. On the retum trip the highway was wider and in better condiftion, so he was able to average 10 km/h faster. What was his average speed on cach part of the trip?Question 21 Assume the position of a person traveling along a straight hiking trail is given by the graph depicted. The input to the function is time in hours, and the output is position in miles from the only outhouse on the trail. The trail travels east-west. | Below you will estimate when the displacement of the hiker is positive, negative or zero using the position function. If the time is an interval give the interval in the form (a, b); if there are multiple intervals then separate the intervals with a comma (a, b), (c, d); and, if the times are a series of single values give the values as a, b, c... List from the smallest to the largest values. For the time interval (0, 10), state the times when the displacement of the hiker is positive. State the times when the displacement of the hiker is negative. State the times when the displacement of the hiker is zero.
